The Types classification groups detection and quantitation technologies into five distinct modalities: Enzyme‑Linked Immunosorbent Assay (ELISA), Western blot, Mass spectrometry, Protein microarray, and Surface plasmon resonance (SPR). ELISA remains the dominant method, contributing approximately 45 % of market value due to its scalability, cost‑effectiveness, and established regulatory acceptance. Western blot, while niche, holds about 10 % of the market, primarily supporting validation of protein size and post‑translational modifications in research settings. Mass spectrometry, a high‑resolution quantitative tool, captures around 20 % of revenue, reflecting its growing adoption for multiplexed analyses and absolute quantitation in both clinical and pharmaceutical contexts. Protein microarrays, offering parallel assessment of hundreds of targets, account for roughly 15 % of sales, driven by biomarker panels and personalized‑medicine initiatives. SPR, valued for real‑time binding kinetics, contributes the remaining 10 %, serving specialized applications where label‑free detection is critical. These type segments collectively shape the overall market size by aligning technology capabilities with end‑user requirements.
